Hey there! Nice to meet you!
I'm sorry you are experiencing this.
The only way to recover a hacked account is through the official Microsoft troubleshooter guide:
You can also try submitting an account reinstatement form since the account is locked due to violations:
https://www.microsoft.com/digitalsafety/account-reinstatement?SilentAuth=1&wa=wsignin1.0
If both web forms don't work, I'm afraid there is no other working method to recover the Microsoft account, and Microsoft Support cannot help either.
Thank you for your understanding.
Best regards,
Darhyl
